چکیده
In the title m-terphenyl derivative, C22H17NO4, the dihedral angles between the aromatic rings of the benzoic acid-acetophenone, acetophenone-benzamide and benzoic acid-benzamide units are 45.39 (8), 48.02 (8) and 42.93 (8)°, respectively. The carbamoyl and carboxyl groups are disordered with a refined occupancy ratio of 0.558 (15):0.442 (15). In the crystal, mol-ecules are linked through O-H⋯O and N-H⋯O hydrogen bonds between terminal carboxyl and carbamoyl groups in a bidentate manner, and anti-parallel helices are formed which extend along the b-axis direction.

متن کاملAcylation of carcinogenic hydroxamic acids by carbamoyl phosphate to form reactive esters.
1. Acylation of 2-(N-hydroxyacetamido)fluorene and several other aromatic hydroxamic acids by carbamoyl phosphate was studied and compared with the acylating activity of acetyl-CoA. Acetyl phosphate was also studied. 2. The carbamoylation reaction had a pH optimum of 4.5. The reaction had a lag period of 1h and was then linear for 4h. This linearity ranged between 0.5mm- and 8mm-carbamoyl phosp...
متن کاملSolution-phase synthesis of a combinatorial library of 3-[4-(coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acid amides.
The parallel solution-phase synthesis of a new combinatorial library of 3-[4-(R1-coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acid amides 9 has been developed. The synthesis involves two steps: 1) the synthesis of core building blocks - 3- [4-(coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acids, 6 - by the reaction of 3-(omega-bromacetyl)coumarins 1 with 3-amino(thioxo)methylcarbamoy...

In the title compound, C(10)H(9)NO(5)S·0.5H(2)O, two geometrically different organic mol-ecules are present. The benzene rings and the carboxyl-ate groups are oriented at dihedral angles of 13.44 (4) and 21.15 (18)°. In both mol-ecules, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, both moleucles form inversion dimers linked by pairs of O-H⋯O hydrogen bonds to g...

In the title coordination polymer, [FeCl(2)(C(32)H(22)N(4))](n), the Fe(II) atom lies on a crystallographic twofold axis and a distorted FeCl(2)N(2) tetra-hedral coordination geometry arises. The complete ligand is generated by crystallographic twofold symmetry, resulting in an infinite one-dimensional architecture along [101].
